    ctdb-daemon: Check if updates are in flight when releasing all IPs
    
    Some code involved in releasing IPs is not re-entrant.  Memory
    corruption can occur if, for example, overlapping attempts are made to
    ban a node.  We haven't been able to recreate the corruption but this
    should protect against it.

    ctdb-banning: If node is already banned, do not run 
ctdb_local_node_got_banned()
    
    This calls release_all_ips() only once on the first ban.  If the node gets
    banned again due to event script timeout while running release_all_ips(),
    then avoid calling release_all_ips() in re-entrant fashion.

    s4:rpc_server/netlogon: Fix for NetApp
    
    This patch fixes an issue where NetApp filers joined to a
    Samba/ADDC cannot resolve SIDs. Without this patch the issue
    can only be avoided by setting "allow nt4 crypto = yes" in smb.conf.
    
    The issue is triggered by NetApp filers in three steps:
    
    1. The client calls netr_ServerReqChallenge to set up challenge tokens
    
    2. Next it calls netr_ServerAuthenticate2 with NETLOGON_NEG_STRONG_KEYS
       set to 0. Native AD and Samba respond to this with
       NT_STATUS_DOWNGRADE_DETECTED. At this point Samba throws away
       the challenge token negotiated in the first step.
    
    3. Next the client calls netr_ServerAuthenticate2 again, this time with
       NETLOGON_NEG_STRONG_KEYS set to 1.
       Samba returns NT_STATUS_ACCESS_DENIED as it has lost track
       of the challenge and denies logon with the message
    
       No challenge requested by client [CLNT1/CLNT1$], cannot authenticate
    
    Git commit 321ebc99b5a00f82265aee741a48aa84b214d6e8 introduced
    a workaround for a different but related issue. This patch makes a minor
    adjustment to that commit to delay flushing the cached challenge until
    it's clear that we are not in a NT_STATUS_DOWNGRADE_DETECTED
    situation.
